Evaluation and Energy Potential of Residential Solid Waste in Hayatabad Peshawar.

Abstract

Residential solid waste management is one of the main problems in Pakistan. This study meant to evaluate residential solid waste generation rate, its analysis and untapped energy potential among the households of Hayatabad, Peshawar. A total of 600 home’s solid waste samples were collected to illustrate the residential solid waste (RSW). The average residential solid waste (RSW) generation rate was 2.66 kg/house/day, while average per capita rate was 0.532 kg/capita/day. The overall average composition was food waste constitutes 42% of the total solid waste quantities, where plastic constitutes 15%, paper 13%, yard waste 7%, glass 5%, metal 2%, debris 1% and other components constitutes 15%. Solid waste collection was executed through donkey carts regulated by PDA (Peshawar Development Authority) whereas it was proposed to regulate bike loaders in place of donkey carts to increase solid waste collection efficiency and to improve outdated system. Energy recuperation from waste can accept a section in restricting the impact of Residential Solid Waste (RSW) on the environment with the additional benefit of giving a local wellspring of energy. Likewise, this examination was done to survey, the job which waste could play in giving energy to residents and gives a gauge of the all-out capability of energy from residual waste. Overall Energy Potential of residential solid waste was 2,563,390 Mega-joules/month (2,563 Giga-joules/month). It was observed that the percentage of combustible/unrecyclable waste was approximately 35% - 40%. Estimated power generation from Hayatabad is approximately 6.88 MW. Our proposed model can generate approximately 180 kWh from 1 Ton of combustible solid waste. The proposed MSW Incineration plant with a capacity of 6.8 MWh per day will cost approximately 2.2 billion PKR. Furthermore cost per kWh of this proposed plant will be 16 PKR with the life span of 25 years and payback time of 10 years.
